FEELER MncnAmsM FOR Looms incense,

Be'it known that LflsAAoSNow, a citizen of the United States, and res ding at Lawrence, in thecounty of Essex'and State of Massachusetts; have invented Improve- 1 ment inFeeler Mechanisms for Looms, of

which the following description, in connection with the'accompanying drawings, isa specification, like characters on the drawings representing like parts.

This invention'relates to ieeler mechahasftor one of its objectsthe provision of a feeler mechanism which shall be sensitive to the presenceor substantial absence of the filling on a detect the filling replenishing mechanism in accordance with the detected ing beat, and control condition ofthe filling.

In that type of feeler mechanism wherein the feelei' is given a side swipe or movement longitudinally of the shuttle when the filling is substainiially exhausted I on a detecting beat, :teeler is either, displaced laterally o given its side swipe movement by the front ward pressure against acting to displace the eler on a detecting beat, In thepresent invention, however, the

tee-lei is mounted upon a feeler carrier which is movable toward and from the front of the loom, and feelei actuator acts normally upon the feeler when 1t is in its rearward position to maintain it in feeling rela- ;tion with the adjacent parts, and when the if'eeler is moved frontwardly. by the frontward pressure'on a detecting beat, todlsplace it laterally, or in a direction longi 'tudinally of the shuttle,'provided the filling is substantially exhausted, To give the feeler sufiicient time to embed-its toothed engaging end into the filling, the feeler actuator acts progressively with increased energy,- tending to displace the feeler laterally as it moves i'rontwardly, so that after the teeth of the feeler have 'embedded'themselves, or itself, into th'efilling, the teeler' actuator will not effect lateral movement or displacement of the feeler, provided a working supply is present, but will efiect such movement when the filling is substantially exhausted.

In the drawings Figure lis a perspective view of the feeler sideof a'loom, showing more particularly the present invention and its association with the coiiperating parts;

Rising from the rock shaft 3 is the arm 4:, to which is connectedat 5 the latch 6, the rear endportion of which is adapted to be engaged at times by an actuator 7 which may be conveniently formed as'part of or connected to the cam follower, as usual in this general type oi. loom. In the present nstance, the

latch 6 has a rear engaging portion Swhich is pivoted to the latch, at '9,"and is normally under balance, so that the rear end 8 normally'below the path of theoperating member 7, Pivotally connected to the support 10 at '11 a bellcranlclever, one' arm 12 of which underlies a finger 13 of therear end portion 8 of the latch 6. The 7 other arm '14 of the bell crank is connected to the feeler mechanism-by a transmitter 15 which may be conveniently formed as a rod or other suitable device, the construction being such that the rear end portion 8 of the latch 6 will normally occupy a position Out of the path of movement of the operating member '7 and will be moved into the path of movement of the" operating member when the feeler is given its side swipe movement, as will presently appear.

The lay 16 may be of usual construction and have the shuttle-130x17 intowhich is picked the shuttle 18 which carries the fill-' ing carrier or bobbin 19. The front wall of the shuttle-box is provided with an opening 20 and the adjacent wall of the' shuttle is provided with an opening 21, the construction being such that whenthe shuttle is properly boxed,the openings will register to permit the entrance therethrough of the feeler. V I

The feeler in the present invention, is

mounted upon a feeler carrier which is movable toward and from the front of the loom.-

There are two principal forms of such carriers 'known in the art,-one a slide, and

' means tor the ileeler carrier 31.

the other a swinging arm. In the present illustration, the slide form of feeler' carrier is shown.

The shipper stand 22 has extending therefrom the bracket 23 which is provided with a slot 24 to which is adjustably secured the feeler support 25 by means of a bolt or other form of securing means 26. r

The feeler carrier is mounted for reciproeating movement toward and from the front of the loom upon a feeler stand 27, which may be adjustably secured to the bracket or support 25. In the present instance of'the invention, the feeler stand 27 is formed with the turned end portions 28 which extend below the support 25 and to which they may be adjustably secured by any suitable means. The front; end portion of the feeler stand is provided with projection 29, and the rear end portion oi thestand is similarly provided with a projection 30, the two projections serving as appropriate guiding In the present instance of the invention, the two projections 29 and 30 are each provided a with an opening through which the feeler carrier 31 extends, and in whichflit is sup-- ported for reciprocating movement.

' The feeler 32 is pivotally connected to the feeler carrier 31 at 33, the pivotal connection being located between the rear and front end portions or the feeler 32. .The rear end portion oi the feeler provided I with engaging teeth 34-, of any suitable character. I

As a convenient form of v't'eeler carrier and pivotal support of the feeler with reference thereto, the feeler carrier 3i is shown as formed of an upper and lower portion which may be formed integral andbent at the front end portion 35. Between the upper and lower portions of the iecler carrier the feeler 32 is located as indicated in Fig.

' l. This construction is a convenient way 1 he changed v otlieih-n'in' 39 ot the feeler actuator extends of relating the parts, but of course, it may Pivotally mounted at 36 on the feeler stand, thefeeler actuator, the reararm 37 of which has a bearing portion 38 which bears upon the side of the feeler 32. The

llfUllllWLlWllY. and is under the influence of yielding means tending to force the end 38 of the actuator against the edge of vthe feeler, In the present instance of the invention, the 'leeler carrier has pivot-ally connected to it at 470, the rod 41 which extends through a lug 42 carried by the frontwardlyextending arm 39 ofthe' feeler actuator. A

spring 43 is interposed between the shuttle 44 and the lug 42, the construction being such that the springnormally tends to force the end 38 of the feeler actuator against the side or edge of the feeler.

When the parts are in normal position with the lay back, the end 38 of the feeler actuator rests or bears upon the side of the feeler 32 at one side of its pivotalconnection with the feeler carrier, and when-the feeler is moved frontwardly on a detecting beat, the end 38 of the feeler actuator-bears upon the feeler at the other side ofits pivotal connection with the feeler carrier. In the present instance of the invention, the end 38 of the feeler carrier bears against the side of the feeler frontward of its pivotal connection' 33 with the'feeler carrier when the parts are in rearward feellngpositlon,

and therebytends to hold the feeler in its proper jfeeling position. To preventpdis placement of the feeler from such position.

under the pressure of the end 38 of the actuator, a stop is provided which,'in the presentinstance'of the invention, consistsof a lug 45 which extends from the feeler and engages a side of the feeler' carrier under the pressure of the feeler actuator when the parts are in normal position, as indicated in Fig. 1.[ When, however, the feeler is pushed frontwardly on a detecting beat, the end 38 of the feeler actuator bears upon the feeler rearwardly of its pivotal connection-33 with members of the feeler carrier 31 and act as a a guide to steady the swinging movement of the feeler actuator under the gradually and progressively increased tension placed upon the spring 43 as the feeler moves frontwardly on adetecting'beat.

The feeler carrier is provided with a step 48 to limit its rearward movement and in to contact with the front projection or lug 29 of the feeler stand when the -feeler carrier is in its rearward position. The construction hereinbeit'ore described presents a good, practical form of the mvention, although in some of the details the from the'true'scopethereof. WVhen aworking supply of filling is present in the shuttle on a detecting beat, the toothed end portion-of 'the feel'er 32 engages the filling and 1s moved frontwardly thereby. 'Asthe feelermoves frontwardly, the feeler' actuator, whichbefore acted frontwardly of the pivot connection between the feeler and feeler ca1r1er,;1s
